It is in the second reading that we read about the actual process of purification the metzora undergoes. Since the seven readings of each parashah correspond to the seven emotive sefirot, the second reading illustrates aspects of the sefirah of might (gevurah). Here, the act of might is the ritual slaughter of the metzora’s offering: “And he shall slaughter the lamb in the place where he shall slaughter the sin offering and the burnt offering.”
When describing the location where the guilt offering is to be sacrificed, the Torah uses what seems to be very cumbersome language: “He shall slaughter the lamb in the place where he slaughters the sin offering and the burnt offering” (וְשָׁחַט אֶת־הַכֶּבֶשׂ בִּמְקוֹם אֲשֶׁר יִשְׁחַט אֶת־הַחַטָּאת וְאֶת הָעֹלָה). Implicitly, the Torah is describing the area to the north of the courtyard altar, and could have just said, “He shall slaughter the lamb in the north.” (וְשָׁחַט אֶת הַכֶּבֶשׂ בַּצָּפוֹן). Using the wording it does, the Torah lengthens the description by 18 letters!
The north side of the altar, which is implied, is associated with might (gevurah) as well. By using the long wording, the Torah is emphasizing the affinity between the guilt offering and the sin offering mentioned in the fifth reading of parashat Vayikra. This link between the two readings, the second of Metzora and the fifth of Vayikra, which corresponds to the sefirah of acknowledgment (hod) alludes to the secret of the connection between these two sefirot, which lie one under the other on the left axis.
